Longtime supporter of CC and NYTimes best selling author Cory Doctorow has released his latest work of fiction, For The Win, under a CC BY-NC-SA license. For The Win is about a virtual future of gamers, Big Sister, and shadow economies. Cory encourages you to remix the work and also to convert it to your favorite format. You can download the book for free, donate, or buy the book at his site.
His last book, Little Brother, was available for download under the same license and spent four weeks on the New York Times bestseller list. For more on why Cory uses CC for his works, see his posts for Locus Magazine on Creative Commons and Why I Copyfight.
